    5. A hierarchical framework for estimating neuroretinal rim area using 3D spectral domain optical coherence tomography (SD-OCT) optic nerve head (ONH) images of healthy and glaucoma eyes

      A hierarchical framework for estimating neuroretinal rim area using 3D spectral domain optical coherence tomography (SD-OCT) optic nerve head (ONH) images of healthy and glaucoma eyes

      Glaucoma is a chronic neurodegenerative disease characterized by loss of retinal ganglion cells, resulting in distinctive changes in the optic nerve head (ONH) and retinal nerve fiber layer (RNFL). Important advances in technology for non-invasive imaging of the eye have been made providing quantitative tools to measure structural changes in ONH topography, a crucial step in diagnosing and monitoring glaucoma. 3D spectral domain optical coherence tomography (SD-OCT), an optical imaging technique, has been commonly used to discriminate glaucomatous from healthy subjects. In this paper, we present a new approach for locating the Bruch’s membrane opening BMO and then estimating ...

    6. Spectral domain optical coherence tomography imaging in optic disk pit associated with outer retinal dehiscence

      Spectral domain optical coherence tomography  imaging in optic disk pit associated with outer  retinal dehiscence

      A 37-year-old Bangladeshi male presented with an inferotemporal optic disk pit and serous macular detachment in the left eye. Imaging with spectral domain optical coherence tomography (OCT) revealed a multilayer macular schisis pattern with a small subfoveal outer retinal dehiscence. This case illustrates a rare phenotype of optic disk maculopathy with macular schisis and a small outer retinal layer dehiscence. Spectral domain OCT was a useful adjunct in delineating the retinal layers in optic disk pit maculopathy, and revealed a small area of outer retinal layer dehiscence that could only have been detected on high-resolution OCT.

    7. Influence of axial length on thickness measurements using spectral domain optical coherence tomography

      Influence of axial length on thickness measurements using spectral domain optical coherence tomography

      Purpose:To assess the influence of axial length on spectral domain optical coherence tomography (SD OCT) thickness measurements in patients with subretinal visual implant. Methods:Data from eight emmetropic pseudophakic eyes of eight patients with subretinal visual implant were analyzed retrospectively. These patients participated in the monocentric part of a multicentre trial (www.clinicaltrials.gov number: NCT01024803). The axial length was measured in three short (< 22.5 mm), three medium (22.51-25.50 mm) and two long (> 25.52 mm) eyes. Using Heidelberg Spectralis, the known thickness of subretinal implant microchip (70 µm) was measured on 15 images per eye ...

    8. Comparison of choroidal thicknesses using swept source and spectral domain optical coherence tomography in diseased and normal eyes

      Comparison of choroidal thicknesses using swept source and spectral domain optical coherence tomography in diseased and normal eyes

      Background/aims Choroidal thickness measurements are reported to differ between swept source optical coherence tomography (SS-OCT) and spectral domain OCT (SD-OCT). This study aimed to assess the comparability of choroidal thickness measurements using SS-OCT and SD-OCT devices among patients with retinal diseases and normal participants. Methods In a prospective cohort study of 100 subjects, comprising patients with retinal disease and normal volunteers, OCT scans were performed sequentially with the DRI OCT-1 and Spectralis OCT using standardised imaging protocols. Subfoveal choroidal thicknesses were independently measured by masked reading-centre certified graders. Paired t tests and intraclass correlation coefficients (ICCs) were used to ...

    9. Hemifield pattern electroretinogram in ocular hypertension: comparison with frequency doubling technology and optical coherence tomography to detect early optic neuropathy

      Hemifield pattern electroretinogram in ocular hypertension: comparison with frequency doubling technology and optical coherence tomography to detect early optic neuropathy

      Background: To assess the sensitivity and specificity of hemifield pattern electroretinogram (HF-PERG) for detecting early retinal ganglion cell (RGC) damage in ocular hypertensive (OH) patients. Methods: Fifty-two OH patients (mean age 56±9.6 years) with an intraocular pressure (IOP) >21 mmHg were assessed. All subjects underwent HF-PERG, optical coherence tomography (OCT), and frequency doubling technology (FDT) visual field. Results: OH patients showed a significant increase of peak-time of the N95 ( P =0.027) compared to controls. The amplitude of the N95 of the lower and upper HF-PERG showed significant differences ( P =0.037 and P =0.023, respectively) between ...

    10. Difference in Subfoveal Choroidal Thickness between Two Spectral-Domain Optical Coherence Tomography Systems

      Difference in Subfoveal Choroidal Thickness between Two Spectral-Domain Optical Coherence Tomography Systems

      Purpose To determine the difference in subfoveal choroidal thickness between two spectral-domain optical coherence tomography (SD-OCT) systems in normal eyes and eyes with retinal diseases. Methods Thirty-three normal eyes and 49 eyes with retinal disease (13 eyes with diabetic retinopathy, 28 eyes with epiretinal membrane and eight eyes with macular hole) were enrolled in the study. Subfoveal choroidal thicknesses were measured by 3 observers using the enhanced depth imaging technique of Heidelberg Spectralis® and the high-definition five-line raster scan of Cirrus HD-OCT® using calipers within the program. Differences between the measured values were analyzed with a paired t -test in ...

  3. Quotes about Heidelberg Engineering

    1. I am becoming a big fan of spectral-domain OCT, especially Spectralis [Heidelberg Engineering, Vista, Calif.]...To this point with time-domain OCT, I have not been convinced that you can use this technology to follow patients over time. Now, with the faster image acquisition and better axial resolution we see with SD OCT, there is better quantitative peripapillary retinal nerve fiber layer measurement for glaucoma management. The improved accuracy of the OCT segmentation allows for better long-term evaluation of patients.
